cuz if there's no drawbacks on leaving it in, i say leave one in all the time so when you do throw a CEL, it'll tell you automatically...If you dont have any codes, it wont spit anything out. I believe it only outputs the flashes when the key is in the ON position. Im not sure if it continues when the car is turned over. I assume there would not be any damage to the electrical system, though I dont know.
Seriously? You would be able to see the light. There would be a panel on the ECU that you would be able to see through if you have it. Otherwise the CEL on your cluster will flash.anyone? can u help me
